Do you mean DVI rather than HDMI?
I can't recall if you can have both running simultaneously. At worst there should be a BIOS setup option to enable/disable the Onboard Video.
Can't you just have one cable from the onboard card to the VGA port on the monitor and one from the DVI port on the PCI card and switch the monitor to either DVI or VGA to pull the VGA or DVI signal?
Its been my experience that it was always UnWise to have more than one set of video drivers per os.
Now the onboard is VGA...the card offers 3-
VGA, HDMI & DMI
Jane's will work great using the OnBoard video (which means, I have to go into the bios and reset/reconfigure those video settings)
Jane's will work using the nVidia now (uhh...) but I get rainbow skies (and tunneling if any tweak is applied whatsoever.)
Of course, LOMAC laughs at the onboard. I'll get the interface and the CTD if I try to jump into the pit.
Allied Force will play nicely w/the onboard, if you turn off clouds, trees, shadows, reflections...otherwise CTD (sometimes).
I look like some monkey staring at a human skull with this thing. JFA18 has some neat stuff that makes me want to continue this excercise in therapeutic hell.
I tried using the two cable thing. VGA cable going to the MB, and either DMI or HDMI going to the card.
But how do you tell windows which one to use?....w/o going into device manager and removing.
Its a true pain in the ass. Unless someone knows a better trick, pass it on down.
I thought I could go into window's system properties and set up seperate user profiles, but I wasn't successful.
I haven't setup multiple user accounts yet. That might be of help. Dunno.
And the energy to do so is more than I have at the moment.
But I'll admit...getting back into Jane's F/A 18 has been more fun that I had anticipated.
High Details but I turn off those whimpy clouds. Bump the sliders just a tad.
She's smoothe as silk, all element displays are extremely fluid. From the chaff/flares to the cloud layer extensions, missle trails to the 3d lighting, lights shimmering on the waters to the perfectly gradienced sun glares...and with all the toys to play with...those coders really had their act together. Judging one corner to the other- Jane's F/A-18 would please any hardcore simmer.
